air compressor moisture seperator question

[donthekawguy]

My compressor is in the house and my blast cabinet is in the garage so I have to run a line out. I get a LOT of moisture in the line probably from the compressor being hot and the lines being cold. I have a filter regulator at the compressor and a small moister separator about 25 feet from the blaster. I have to stop about every 15 minutes and empty the separator and take the tip out of the gun to get the wet sand out. Should I be using a bigger separator or maybe install another one on the blast cabinet? took all day to blast a bunch of parts and I'm looking for a better way.
